METHOD FOR PREPARING FILLING AGENT FOR POLYMERIC COMPOSITION Russian patent published in 2007 - IPC C01B33/193 C09C1/28 C09C3/10 

FIELD: chemistry of polymers, chemical technology.

SUBSTANCE: invention relates to a method for preparing a filling agent used in manufacturing polymeric composition materials in making articles for structural and tribotechnical designation. Method involves mixing 0.5-10.0 mas. p. of epoxy diane resin with 100.0 mas. p. of sodium silicate aqueous solution (by dry matter) at temperature 40-60°C. Then the mixture is coagulated with mineral acid taken in the amount providing hydrogen index pH = 4.0-5.0, washed out with water and prepared solid substance as a precipitate is dried. Invention provides enhancing physicochemical and antifriction properties of the polymeric composition.

EFFECT: improved preparing method.
